Trimmed the trailing edge of each wingtip to match the trailing edge of the ailerons. Installed, marked and cut the left wingtip hinge pin for installation in the anchor block. Did some planning on the alternate air door control cable. Think I found a good spot for the firewall pass through. You can just barely make out my mark on the firewall in the photo. Gonna use the tab on the engine sump for an Adel clamp to route it to the alt air door.
